Abstract

506,042. Loud - speakers. LEEVERS, F. N. G. Nov. 19, 1937, No. 31909. [Class 40 (iv)] A loud-speaker cabinet has one or more flared passages extending from the back of the diaphragm of the loud-speaker unit in a direction substantially at right angles to the axis of the diaphragm which passes therethrough at right-angles to the plane of the periphery of the diaphragm. As shown in Fig. 2, the cabinet having front and back walls 1, 8 is provided with vertical partitions 7 forming passages from the rear of the diaphragm to apertures 5 in the side walls of the cabinet. In a modification, Fig. 5, the partitions 7 are inclined to the vertical and passages terminate in openings 5 in the top and bottom walls of the cabinet which has a horizontal cross-section of triangular shape. In a further modification, Figs. 4, 6 (not shown), the loud-speaker is mounted near the base of the front wall of a cabinet having sides which diverge upwardly and provided with an opening in the top wall.
